java - How to unit test a class which extends/inherits a 3rd party class -

-

i have created new class extends 3rd party abstract class. new class calls methods in abstract class. problem have when trying write unit test, i'm not sure how write test not know exact details 3rd party class requires.

the abstractdecoratormapper below sitemesh specific class have extend sitemesh work correctly. far can tell documentation can't use composition. 

public final class partnerdecoratormapper extends abstractdecoratormapper {      @override     public void init(config config, properties properties, decoratormapper parent) throws instantiationexception {         super.init(config, properties, parent);     }      @override     public decorator getdecorator(httpservletrequest request, page page) {         if (super.getdecorator(request, page).getname().equalsignorecase("default")) {             return getnameddecorator(request, "externalpartnerdefault");         }         return super.getdecorator(request, page);     } }

i use jmock if there tool can help.

there 2 things might asking. i'll try answer both.

possible question 1) how test additional functionality?

possible question 2) how test the combined functionality appropriate?

let me start question1.

i suggest simple peel. there video of technique here: http://www.youtube.com/watch?v=p0tilwrzh5q (the video c# identical in java)

which mean have following code afterwards

@override public decorator getdecorator(httpservletrequest request, page page) {     decorator d = super.getdecorator(request, page);     return getresolveddecorator(d, d.getname(), request);  } public decorator getresolveddecorator(decorator current, string name, httpservletrequest request) {     if (name.equalsignorecase("default")) {         return getnameddecorator(request, "externalpartnerdefault");     }     return current; }

now can test call like

assertequals(expected, new partnerdecoratormapper().getresolveddecorator(null, "default", mockhttpservletrequest);

i suggest possibly removing data httpservletrequest well, make testing & intent clearer.

note: has added performance benefit call super.getdecorator() occurs once, since result cached.

additional note: worth noting override of init() unneeded, , doesn't anything.

question 2: harder question, don't state desired behavior is. assuming factory pattern, work in manner like

| http request quality 1 | page quality 1| expected decorator | | /mypath/mypage | status = foo | mydecorator |

(i have no idea above chart should contain or like) once have behavior test ensure rather straight forward.

happy testing, llewellyn

django - How can I change user group without delete record -

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

java - Need to add SOAP security token -

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
